IMPROVEMENT IN SOLDERlNG-IRONS.

Specification forming part of Letters Patent No. 219,815, datedSeptember 23, 1879; application filed August 5, 1879.

To all whom it may concern:

Be it known that I, J ornv J OSEPH HENRY,

of Baltimore city, State of Maryland, have invented certain newand'useful Improvements in Soldering-Irons; and I hereby declare thesame to be fully, clearly, and exactly described as follows, referencebeing had to the accompanyin g drawing, in which the device isillustrated in side elevation.

My invention relates to that class of soldering-irons in use for cappingprovision-cans; and it consists in certain improvements upon the ironfor which Letters Patent were gran ted me April 1, 1879, and numbered213,902.

In the practical working of the class of soldering-irons to which mypresent invention and my patented improvement belong, an obstacle wasmet in the matter of the wearing of the center rod from the revolutionabout it of the handle.

My former invention had for one of its objects to obviate this evil byproviding means for taking up the wear as it occurred.

In the present case I cause the rod to revolve with the handle, insteadof the handle about the rod, whereby the wearing of the rod is whollyprevented.

The invention consists in certain features of construction, which aremade the subject of the claims.

In the drawing, A' is a rod, preferably of steel and cylindrical inshape, except that it has a flattened side, at, extending from a to a".As an alternative for this construction the rod may be polygonal incross-section but the described construction is preferred, as it admitsof the device being used in the old way, the handle D being caused torevolve about the rod-a feature which becomes of importance should thepoint 0 become rusted, or for some reason refuse to revolve.

B is a handle, of wood or some other bad conductor of heat, which isprovided with a thimble,b,in which the end of the rodAturns, beingheadedat b above the thimble, as shown.

C is the tip, having a pyramidal point, e, to be stepped in the centerhole of the can-cap and admit of the escape of the air. The end 0 of therod Ais stepped in the tip, as shown, and has an annular groove, d. Apin, 0',

through the tip engages with this groove and holds the tip on the rod.

D is the tool-holder handle, havinga bushing, d, at its upper end, andcarrying at its lower end the sleeve E, through which latter a screw, 6,passes, and, engaging with the fiat side of the rod A, preventsrevolution of the handle D about the rod unless retracted. The screw isnot driven into contact with the rod, whereby, while preventingrevolution of the handle, it admits of its being slid back and forth onthe rod.

Arms 0 e are made integral with the sleeve E and sustain the tool-holderF. The shank of the latter is slotted at g g,and through the slots passscrews 11. h, whereby the holder may be adjusted laterally while stillbeing maintained parallel to the axis of revolution. This enables theuser to adjust the device for soldering various-sized can-caps whilehaving the iron vertically over the.seam in each case.

The advantage of this will be apparent when it is remembered that theedge of the iron is somewhat curved, and a motion of the tool withreference to the axis of rotation after the manner of a pair ofdividers, as heretofore, causes the center of the soldering-edge to riseslightly and the corners to catch in the groove.

The pyramidal point 0 has an ulterior function beyond that of allowingthe air to escape from the can. It catches in the tin and enforces therotation of the rod with reference to itself, preventing its operatingafter the manner of a reamer, and enlarging the hole in the can-cap.

The operation of the device is as follows: The iron G being heated, andthe cap laid in place on the can, solder is applied to the groove, andthe rod being stepped in the cen ter hole of the cap, the iron isrevolved by means of the handle D upon the solder until it is evenlyspread in the groove.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a soldering-iron, a tool-holder handle mounted upon and arrangedto rotate with a center rod, which latter is provided with a swivelingtip, as set forth.

2. In a soldering device, a rod carrying the solderin g-iron, andarranged to revolve therewith, and provided with a swiveling tip andterminal handle, substantially as described.

3. In a soldering-iron, a center rod having a swiveling tip, andcarryinga tool-holder handle which slides upon the rod, as set forth.

4. In a soldering-iron, a center rod having a swiveling tip,andcarryin ga tool-holder handle provided with mechanism for clamping the handlewith reference to the rod, substantially as described.

5. In a solderingiron, a center rod having a flattened side, asdescribed, and swiveling tip and terminal handle, in combination with atool-holder handle arranged to slide upon the rod and be rotated withthe said rod or independent of it, as and for the purpose described.

6. In combination with the handle D,sleeve E, and tool-holder F, theflattened rod A and screw 1:, as described.

7. In combination with the center rodAand handle D, the sleeve E,arms ee,slottedholder F, and screws h h, as set forth.

8. In a soldering-iron, a center rod adapted to hold the can capinplace, and provided with a swiveling tip, and a to0l-ho1der handlearranged to revolve with the said rod and to slide freely upon it, asset forth.

9. The soldering device herein described, consisting of the rod A,arranged to revolve with the handle D, and having the swiveling handleB, the sleeve E, and swiveling pyramt dal pointed tip 0, and thetool-holder F, laterally adjustable parallel to the rod, substantiallyas described.
